I still prefer Apple iphone or iOS over Android...

given me that I have just switch from phone5 to OnePlusOne

It is a good phone on android with rock solid hardware that blew the world but but...

1: I still feel slower than iphone or just as fast not faster given the hardware... WHY?
2: App crash very frequent and weird things happen to the App like button dont work etc etc... and suddently the app just LAGGGGGGGG for few seconds...
3: Receiving phone call the screen become un-responsive.. it happen to my one plus one... it happen to my friend nexus5 it happen to my cousin nexus4
4: I need to reboot my android phone 1 a week or more... appereantly it is normal.... NO IT IS NOT NORMAL!!!
5: it crash on OS level... yes it become weird like sound dont work vibration dont work.. etc minor stuff but it annoy!!!!

yes conclusion although Apple spec is not high but the optimization level is damn solid!
